Hi: Everytime I insert a DVD that I burned (a movie) I get a message that the disc isn't formatted. It plays fine on my desktop (Dell) but not on my laptop (IBM Thinkpad). I downloaded AviCodec which showed everything enabled. Then I tried GSpot which showed some missing files, but no advice on where to find them. There were quite a few. It also gave me the message that Windows is unable to read the DVD because its either corrupt or not formatted. I get this with every DVD I insert. HELP PLEASE!!! I don't know what to do anymore....I even tried all kinds of codec programs including K-Lite Mega Codecs which did nothing.
